House costars Jennifer Morrison and Jesse Spencer have called off their engagement, PEOPLE has learned exclusively.

"After much consideration, we have decided not to get married," the couple said in a joint statement. "We are still very close, and we look forward to continuing to work together on House."

Spencer, 28, who proposed to Morrison, also 28, over the holidays at the Eiffel Tower in Paris, recently said that it had taken him six months to ask Morrison to marry him.

They had planned to wed later this year.
